Portable Hot Water

[Lvfunnyfarm]

I'm interested in a portable hot water system.
It can be homemade or off the shelf.
What's everyone using?
Would like to see some pics!

I've seen some made with copper pipe put over a fire as a "redneck/off grid water heater". I meant to try to build one fore my last trip but ran out of time.

I heat up water on camp stove. Bring it to a boil to kill the germs in the pot and then mix it with about as much cold water in a fabric bucket = 2.5 gallons of nice warm water.
